Is being overweight associated with engagement in self-injurious behaviours in adolescence, or do psychological factors have more “weight”?

Introduction The purpose of this study was to examine the prevalence of non-suicidal self-injurious behaviours (NSSI) among healthy weight and overweight adolescents and to examine the role of age, gender, weight status, treatment condition for weight control, and psychological variables (psychopathological symptoms and emotional skills) in the prediction of NSSI. Methods The study had a cross-sectional design, and participants (n = 370) were aged 14-19 years and were divided in three groups: 205 adolescents with normal weight, 82 adolescents from the community with overweight/obesity, and 83 adolescents with overweight/obesity and in outpatient treatment for weight control. Results The prevalence of these behaviours in the overweight community group (25.6 %) and in the overweight clinical group (14.5 %) was similar to their healthy weight peers (19 %). Not attending an outpatient treatment for weight control, higher psychopathology and less ability to regulate emotions predict the presence of NSSI. Conclusion Being overweight is not associated with NSSI, but psychosocial variables such as psychopathology, emotional deregulation and the absence of medical care predict these behaviours.info:eu-repo/semantics/publishedVersio

Skeletal Light-Scattering Accelerates Bleaching Response in Reef-Building Corals

Background At the forefront of ecosystems adversely affected by climate change, coral reefs are sensitive to anomalously high temperatures which disassociate (bleaching) photosynthetic symbionts (Symbiodinium) from coral hosts and cause increasingly frequent and severe mass mortality events. Susceptibility to bleaching and mortality is variable among corals, and is determined by unknown proportions of environmental history and the synergy of Symbiodinium- and coral-specific properties. Symbiodinium live within host tissues overlaying the coral skeleton, which increases light availability through multiple light-scattering, forming one of the most efficient biological collectors of solar radiation. Light-transport in the upper ~200 μm layer of corals skeletons (measured as ‘microscopic’ reduced-scattering coefficient, μ′S,m), has been identified as a determinant of excess light increase during bleaching and is therefore a potential determinant of the differential rate and severity of bleaching response among coral species. Results Here we experimentally demonstrate (in ten coral species) that, under thermal stress alone or combined thermal and light stress, low-μ′S,m corals bleach at higher rate and severity than high-μ′S,m corals and the Symbiodinium associated with low-μ′S,m corals experience twice the decrease in photochemical efficiency. We further modelled the light absorbed by Symbiodinium due to skeletal-scattering and show that the estimated skeleton-dependent light absorbed by Symbiodinium (per unit of photosynthetic pigment) and the temporal rate of increase in absorbed light during bleaching are several fold higher in low-μ′S,m corals. Conclusions While symbionts associated with low-μ′S,m corals receive less total light from the skeleton, they experience a higher rate of light increase once bleaching is initiated and absorbing bodies are lost; further precipitating the bleaching response. Because microscopic skeletal light-scattering is a robust predictor of light-dependent bleaching among the corals assessed here, this work establishes μ′S,m as one of the key determinants of differential bleaching response

From tackles to trauma: investigating the influence of the FIFA World Cup 2022 on public maxillofacial department in Qatar - an observational study.

The Federation Internationale de Football Association (FIFA) World Cup (FIFA-WC) is considered the pinnacle of international sporting events, attracting a diverse array of attendees from across the globe1. Hosting such an event presents diverse challenges for the organizing country, which are further amplified by public health threats1. The 22nd FIFA-WC, held in Qatar from 20 November to 18 December 2022, distinguished itself in several unprecedented dimensions. It marked the first instance of a FIFA-WC being conducted amidst the throes of a global pandemic, specifically the COVID-19 crisis1,2. Moreover, Qatar’s demographic and geographic attributes further accentuated its unique position as the smallest nation, both in terms of population and territory, to host such a monumental event1,2. Notably, the event was devoid of the previously mandated COVID-19 restrictions, as they were lifted in September 2022, presenting an unparalleled scenario for the healthcare sector

Pandemic-related racial discrimination and its health impact among non-Indigenous racially minoritized peoples in high-income contexts : a systematic review

This study aims to review articles reporting the perspectives and experiences of pandemic-related discrimination among racially minoritized peoples in high-income contexts. We searched online databases (Medline, EMBASE, PsycINFO, Web of Science, and ProQuest) for peer-reviewed articles published between January 2002 and October 2020. Eligible studies reported either quantitative or qualitative accounts of pandemic-related discrimination from the perspectives of racially minoritized peoples in high-income contexts. Two authors screened 30% of titles/abstracts, and all full-text articles. Each article included for extraction underwent a quality assessment by two reviewers. Data were extracted and categorized thematically using NVivo 12, followed by a secondary analysis informed by critical race theory. Of the 1289 articles screened, 16 articles from five countries met the inclusion criteria. Racial discrimination is heightened during pandemic periods, due to the social association of specific racial groups with pandemic diseases including COVID-19, SARS (Asian), H1N1 (Hispanic) and Ebola (African). Fear based responses to racially minoritized peoples during pandemic periods included verbal/physical abuse, hypersurveillance, and avoidance, often occurring in public spaces. Pandemic-related racism had subsequent impacts on mental health and health care accessibility. Various coping strategies, including community support, avoidance, and problem solving, were documented in response to racial discrimination. Racialized discrimination and violence is a serious threat to the health and wellbeing of racially minoritized peoples, particularly due to its increase during pandemic periods. Racism must be recognized as a public health issue, and efforts to address its increased impact in pandemic contexts should be made, including ensuring that adequate representation of racially minoritized groups is present in policy, planning, and implementation

Supplementary Material for: Dysphagia secondary to A large anterior cervical osteophyte: A case report.

Diffuse idiopathic skeletal hyperostosis (DISH) is a common systemic condition that leads to ossification of the anterior spine longitudinal ligament with anterior marginal osteophytes formation. Generally, these osteophytes are asymptomatic, but when they are extremely large in size, they may lead to mechanical esophagus obstruction and dysphagia. Here we are presenting a rare case of sever progressive dysphagia caused by a giant anterior cervical osteophyte, which was treated with surgical resection of the osteophyte and interbody fusion of the affected cervical segment. Cervical degenerative disc disease and DISH should be included in the differential diagnosis when evaluating an elderly patient for dysphagia. Early surgical intervention with osteophyte resection and interbody fusion is recommended to prevent recurrent osteophytes formatio

Procedures for risk-stratification of lung cancer using buccal nanocytology

Lung cancer is the leading cause of cancer deaths in the U.S. with survival dramatically depending on stage at diagnosis. We had earlier reported that nanocytology of buccal cells can accurately risk-stratify smokers for the presence of early and late-stage lung cancer. To translate the technique into clinical practice, standardization of operating procedures is necessary to consistently yield precise and repeatable results. Here, we develop and validate simple, robust, and easily implementable procedures for specimen collection, processing, etc. in addition to a commercially-viable instrument prototype. Results of this work enable translation of the technology from academic lab to physicians’ office
